Discussion group for Sentiment Analysis: The identification, extraction, and use of opinion, attitude, and emotion in online, social, and enterprise sources via automated natural language processing (NLP), text analytics, content analysis, semantic analysis, crowd-sourcing, and human analyses. With the explosion in use of Facebook, Twitter, and blogging – of TripAdvisor, Yelp, and FlyerTalk – of on-line media and of e-mail, instant messaging, and surveys – it is essential to hear the true Voice of the Customer (and the Market, Patient, and Employee)… and to be heard. Yet keeping up with the round-the-clock information torrent is impossible with old, manual methods. The ability to lead the competition – in customer satisfaction and support, brand and reputation management, financial services, product design and marketing, and an array of other business processes – depends on automated analysis of sentiment, mood, and opinion. The Sentiment Analysis Symposium provides an unmatched opportunity to learn about sentiment technologies, how they are applied, return on investment, and how to choose from among the many available solution options.
